Music player won't do online download& problem#2, updates doesn't update in recovery?

i have a problem where when trying to download any song online in the miui music player i get connect to server error and/or file not recognized error that pops up. What could be a problem, did i need to sign up somewhere to connect to server??

another problem is that whenever the weekly updates come out after i finished downloading the update and i get to recovery and as its about to start installing i get some error where it won't even find it or start.

Ive done factory reset by the way

i want to try to format my sdcard to see if it would fix it
and is their anyway i could format and erase everything off my SD card?because from the settings when i click format it doesn't do ANYTHING. I just have everything still there wtf...
By the way, if i were to format my sdcard would i lose my ext3 partition??
